Tuna is a popular deep seawater fish because of its meaty taste and Omega-3 fatty acid benefits. Tuna fish is available fresh or canned in the market. While consuming fresh tuna fish is always desirable, you can store tuna and finish it later. So, it brings us to the prime question, Can you freeze tuna? Yes, it is possible to freeze tuna.
Generally, fresh tuna is frozen solid to maintain its freshness. Canned tuna, if unopened, does not require any freezing. It can maintain on its own. However, if you have canned tuna leftovers or other dishes made with tuna, they need proper prepping before freezing them. It helps to maintain their texture, flavor, and taste.
Before we discuss how to freeze fresh and canned tuna, here are some points to note.
- Canned tuna and related foods like tuna salad and casseroles can remain fresh when refrigerated for three to five days.
- It is advisable to consume fresh tuna as soon as possible. However, you can refrigerate them for two to three days.
- We do not recommend eating tuna kept at room temperature for more than two hours.
- Fatty fish like tuna can remain indefinitely inside the freezer, but consuming them within three months is better.
How Do You Freeze Tuna?
The freezing method depends on what type of tuna fish you freeze.
Freezing Fresh Tuna
Fresh tuna fish can be prepped in two ways.
Fresh tuna pieces require some prepping before you freeze them. Use a clean towel to pat the meat dry. Water deposits on the parts can form crystals and change the fish’s texture and flavor. Wrap the pieces using aluminum or cling wrap before placing the fish into a resealable freezer bag. Note down the date of freezing.
An alternate method is to dip the tuna pieces in a mixture made by dissolving ascorbic acid crystals (1 tablespoon) or a quarter cup of salt and one quart of water. The solution forms a protective layer over the fish. Then, wrap the meat in aluminum foil or cling wrap. Finally, place the wrapped tuna fish in a resealable zip-lock bag and place it inside the freezer.
Freezing Canned Tuna
Leaving the can unopened does not harm the product. It can remain edible up to the expiry date mentioned on the can. But, if you decide to freeze canned tuna, you cannot keep the tin inside the freezer because the cans are not suitable for freezing.
The appropriate method is to open the can and transfer the contents to a freezer-safe bag or container. It extends the shelf life considerably. Remove the air and seal the container with a cling wrap before closing the lid. Note down the freezing date on the container.
Freezing Tuna Salads Or Canned Tuna Leftovers
If you open canned tuna and have leftovers, you can freeze them for later consumption. Similarly, tuna salads and casseroles can also be frozen.
The trick is to divide the pieces and tuna salads into smaller portions for convenient consumption. Breaking them down into small quantities is that individual batches freeze faster. Therefore, the salads remain fresh for longer durations.
You can fill your zip lock freezer bag or airtight container with the leftovers and salad.
Squeeze the air out of the zip-lock freezer bag and seal it. If you use a plastic container, remove the excess air, cover the container with a cling wrap, and close the lid.
Proceed with placing the freezer bag/container into the freezer compartment. Write down the freezing date on the container before freezing the fish.
How Long Can Tuna Be Frozen?
Frozen tuna remains fit for consumption for up to three months.
How To Defrost Tuna?
Depending on your requirements, you can defrost small portions of tuna. First, remove the required component from the freezer bag and place it in another container in the refrigerator. It allows the tuna to melt naturally in a few hours. However, if you wish to thaw the entire freezer bag, it must be left in the fridge overnight.
Alternatively, you can thaw frozen tuna in a microwave oven. You can also melt tuna by keeping it at room temperature or holding the sealed bag under running water from a tap.
The same principles apply to thawing tuna leftovers, canned tuna, and tuna salads.
Can You Reheat Or Cook Thawed Tuna?
Thawed tuna can be reheated in a microwave oven or cooked according to your preference.
Can You Refreeze Tuna?
Generally, we do not recommend refreezing food once it is thawed. However, there are no such restrictions on tuna. You can refreeze tuna that has been melted naturally inside the refrigerator. Thus, you should not refreeze tuna that has been thawed in a microwave oven or at room temperature, or under a tap.
How Do You Detect Bad Tuna?
Bad tuna can develop dark brown streaks that might appear black at times. If you notice these distinctive streaks, you should avoid eating the tuna. Another symptom of tuna turning bad is that the tune turns green.
What Should Be The Color Of Frozen Tuna?
The frozen tuna should have a reddish tone while being brown. If the tuna turns dark brown, it is advisable to discard it.
Can You Sear Frozen Tuna?
After thawing the tuna inside the refrigerator, you can sear or grill them to prepare delicious meals.
Can I Refrigerate Canned Tuna?
As long as the can remains unopened, refrigeration is unnecessary. But, if you open the can, it has to be refrigerated or frozen according to your requirements.
What Happens If We Freeze A Can Of Tuna?
Freezing a can of tuna can affect its taste. Besides, the liquids inside the can (water, oil, or brine) can expand. There would not be enough room inside. So the can could burst.
Freezing tuna in the freezer should not be a problem if you know the correct procedure. Once you master how to freeze tuna, you will never run short of the seafood again.
